Gate theory
An AND gate is a basic digital logic gate that produces a high output only when all of its inputs are high.

AND Gate Simulator With Truth Table
Explore the AND gate by switching inputs, reading the truth table, and seeing why the output becomes 1 only when every input is 1. Learn the Boolean expression, input-output behavior, and digital circuit logic through a focused OpenLabs interactive simulator.

Understand AND gate logic through live input-output behavior
The AND gate behaves like a strict condition checker: if A and B are both 1, the output is 1; otherwise the output remains 0. The simulator helps students connect symbols, Boolean expressions, truth tables, and circuit output without needing physical hardware.
Understand the Boolean expression and truth table of an AND gate.
Predict the output for every input combination.
Connect AND logic with conditions used in circuits and programs.
Use the simulator to compare theory with live input changes.
